The ones in Westview Park or Kennywood Park in Pittsburgh or many other amusement parks from around the country in the 50's & 60's. They ran on electric .
Had a pole on the back going to a metal electrical charged overhead cage.

Remember driving the bumper cars at amusement parks or
on the Boardwalk, don't you? They were so much fun.

Most parks with bumper cars won't allow you to even bump anyone with them anymore, so they're just as well off used for some sort of vehicle. Many years ago I went to an amusement park, and the big sign said "Bumper Car Ride", then as you boarded, a smaller sign read "no bumping allowed"!!

That STINKS! At Knoebels park it's full on. Bump away as hard as you like. Only thing is they have it set up so that you can only go one way in a circle so there are no head ons.

They run on either Kawasaki or Honda motorcycle engines and co-opt vintage bumper car bodies into the most awesome form of mini-car we've seen in too long. There are seven of these little monsters floating around California and they're all the creation of one man, Tom Wright, a builder in the outskirts of San Diego who figured the leftovers of the Long Beach Pike Amusement Park needed a more dignified end than the trash heap.

They were originally powered by two cylinder Harley Davidson
Motorcycle engines but they rattled like heck because of the two cylinder
Vibration and Tom replaces them with four cylinder Honda or Kawasaki 750's
And a couple have been measured as capable of 160 MPH, which is terrifyingly fast in machines with such a short wheelbase.
